Audio Engineering

Typically an audio production proces consists of three stages: recording, mixing and mastering. During mastering the source material (ideally at the original bitdepth and resolution -or higher) is processed using equalization, compression, limiting and other processes. More tasks, such as editing, pre-gapping, leveling, fading in and out, noise reduction and other signal restoration and enhancement processes (tonal-, temporal- & spatial) can be applied as part of the mastering stage before online distribution or cd-replication.

As iTunes (Store) has entered the Dutch market, many technical questions arise about mastering of audio tracks for distribution via iTunes (Store). Some of the questions are answered in the official documentation and on the official site, but many aspects are not covered there.

Let’s investigate...


(This website is always under revision!).

Welcome! Thank you for visiting the official & secure acoustiColour website.


acoustiColour crossing borders, connecting knowledge, ..and getting inspired by art & science.

Because music is art & sound science, in 1988 acoustiColour is founded by musictechnologist (multidisciplined & certificated: electronics-, audio-, recording-, mix-, mastering engineer, composer, sound designer) and teaching musician Marcel Wardenier.

Project Software Downloads:

Inspired by some of the most groundbreaking innovative audio pioneers/gurus acoustiColour created bootable CD/USB/VM images with clean builds of a hardened Debian Server for experimental dedicated realtime DSP Low-Latency JACK Audio Server Applications.

Disclaimer: as is, because this is work in progress.. (Altough functioning 99.99% stable in my audiolab 24/7!)
Please: don't forget to check out the tutorials & RTFM's!!

(And if you do read them, you'll notice how easy the concept is ported to other hardware platforms ☺!!)

(...acoustiColour simply loves the power of Open Source Software and Debian installed on a nowadays old useless-, but relatively silent Mac Mini 2,1+. Easily 'build' your own DSP power house running 16/24 bits 44.1/48/(96*) kHz., syncing on WC via S/PDIF signal using one of these instant functioning DSP bootable disk images.

(*) Dependent on production date of Mac Mini 2,1+
